The definition of Fra Diavolo is "brother devil," and whenever you have that kind of language being tossed around in the food category it means this is going to be SPICY. So since I am the least spicy person I know, I'm not sure what compelled me to make this shrimp pasta fra diavolo version. My sister is the spice-loving one in our family, but for some reason I decided to make an exception for this...maybe because I love the exotic name? And since I am the cook and the Southern husband is the clean-up crew, I was able to take it just to the edge of my spice tolerance level. Meaning that mine has just enough naughty heat to make you sit up and take notice, but it won't have smoke coming out of your ears. If you are a spicier person than I am, or you are my sister, dial up those red pepper flakes!
